This particular play didn't affect my teams, but it absolutely sucks more losing at FF due to a play at the end of a Monday night game. Countless times over the years I have stayed up to watch a game I could give a rats ass about, knowing Id be a tired mess at early Tuesday morning work meetings, only to lose at the end of the game at midnight. It blows, and yes, it wouldn't suck nearly as much if the game was played on Sunday. I think that was the point of the post and I get it.
Simple gambling really. If you bet on 1 game and it has your full attention and you lose, it seems to hurt more than when you bet on 5 Sunday games that all go on at once where your attention is divided and you can think "well, I can always make it up in another game."
